Part of the problem is that the benefits of better plant growth, thanks to higher carbon dioxide concentrations (plants use CO2 for photosynthesis) are more than offset by the impact of higher temperatures and differing precipitation.

As the climate warms, researchers expect more dusts to make their way aloft, possibly having impacts on precipitation by changing where rain or snow falls.

Acid rain is now caused by nitric rather than sulfuric acid — and it comes from more sources than the earlier acidic precipitation did

Another advantage to a shared sewer is that such systems are usually built to withstand heavy loads and can better accommodate periods of heavy precipitation or storm surges that might overwhelm smaller, poorly conceived or maintained home - based septic tanks, which are by virtue of their size and the laws of physics more prone to overflow and send contaminants into nearby surface and ground waters.

Extreme weather does not prove the existence of global warming, but climate change is likely to exaggerate it — by messing with ocean currents, providing extra heat to forming tornadoes, bolstering heat waves, lengthening droughts and causing more precipitation and flooding.

Climate scientists know that the intensity of extreme precipitation events is on the rise because there's more water vapor in the atmosphere caused by higher global and sea temperatures.

The study concludes that the growth of the Mauna Kea glacier caused by the AMOC current changes was a result of both colder conditions and a huge increase of precipitation on Mauna Kea — triple that of the present — that scientists believe may have been caused by more frequent cyclonic storm events hitting the Hawaiian Islands from the north.

So apparently you're suggesting that decadal - scale precipitation patterns (more, less rainfall) and temperature changes are better explained by atmospheric CO2 concentrations.

With higher precipitation, portions of this snow may not melt during the summer and so glacial ice can form at lower altitudes and more southerly latitudes, reducing the temperatures over land by increased albedo as noted above.

I was thinking instead perhaps more easily controlled polar - orbit satellites might be used, which would rotate with some fixed ratio to their orbital period, casting greater shadows at higher latitudes... or some other arrangment... for a targetted offset polar amplification of AGW especially and in particular perhaps avoiding the reduction in precipitation that can be caused by SW - radiation - based «GE» (although aerosols that actually absorb some SW in the troposphere while shielding the surface would have the worst effect in that way, I'd think)... strategic distribution of solar shading has been suggested with precipitation effects in mind, such as here... sorry, I don't have the link (I'm sure I saved it, just as Steve Fish would suggest — but where?).

However, it has been known since the earliest general circulation simulations by Manabe that as the Earth warms in response to increasing CO2, the precipitation increases much more slowly than Clausius - Clapeyron would suggest — typically only 2 - 3 % per degree of warming.

A gentle global increase in precipitation with warming can be made up by localized systems becoming more intense while vast other areas get drier and more sluggish.

But that again is a rather weak argument, because drought is far more complex than just being driven by average precipitation.

However, higher temperatures do cause an increased chance of heavy precipitation events, and it is likely that the flooding in some of this year's U.S. flooding disasters were significantly enhanced by the presence of more water vapor in the air due to global warming.

Prompted by Foster / Wright above, I have since looked at a greater range of the literature and found a significantly more southerly source of Greenland precipitation in most papers (again without claiming an exhaustive search, so I may be missing something.

Unfortunately, the figure also confirms that the spatial resolution of theoutput from the GCMs used in the Mediterranean study is too coarse for constructing detailed regional scenarios.To develop more detailed regional scenarios, modelers can combine the GCM results with output from statistical models.3 This is done by constructing a statistical model to explain the observed temperature or precipitation at a meteorological station in terms of a range of regionally - averaged climate variables.

Scientists expect more intense storms to occur in the Midwest throughout the year, and more precipitation to fall in winter and spring.4 If our carbon emissions continue to rise at current rates, spring rainfall in Jefferson City is projected to increase 25 percent or more by the end of this century.9, 10

Also part of the explanation is the claim that more humid air results in more precipitation, but again I'm unclear on why warmer air can cause more water to be evaporated, but warmer air does not by the same mechanism prevent the same water from condensing.

The results indicate that extreme precipitation events consistently increase by the middle of the twenty - first century for all return periods (49 — 52 %), but changes may become more profound by the end of the twenty - first century (81 — 101 %).

These facts help explain why, in spite of the Earth's air temperature increasing to a level that the IPCC claims is unprecedented in the the past millennium or more, a recent study by Randall et al. (2013) found that the 14 % extra carbon dioxide fertilization caused by human emissions between 1982 and 2010 caused an average worldwide increase in vegetation foliage by 11 % after adjusting the data for precipitation effects.

Scientists agree that the effects of climate change will include more sporadic and irregular precipitation, with longer periods of drought separated by more intense rainfall; and increasing average temperatures.

This is one of the more challenging aspects of modeling of the climate system because precipitation involves not only large - scale processes that are well - resolved by models but also small - scale process, such as convection, that must be parameterized in the current generation of global and regional climate models.

Precipitation occurs about once every seven days in the western part of the region and once every three days in the southeastern part.77 The 10 rainiest days can contribute as much as 40 % of total precipitation in a given year.77 Generally, annual precipitation increased during the past century (by up to 20 % in some locations), with much of the increase driven by intensification of the heaviest rainfalls.77, 78,79 This tendency towards more intense precipitation events is projected to continue in Precipitation occurs about once every seven days in the western part of the region and once every three days in the southeastern part.77 The 10 rainiest days can contribute as much as 40 % of total precipitation in a given year.77 Generally, annual precipitation increased during the past century (by up to 20 % in some locations), with much of the increase driven by intensification of the heaviest rainfalls.77, 78,79 This tendency towards more intense precipitation events is projected to continue in precipitation in a given year.77 Generally, annual precipitation increased during the past century (by up to 20 % in some locations), with much of the increase driven by intensification of the heaviest rainfalls.77, 78,79 This tendency towards more intense precipitation events is projected to continue in precipitation increased during the past century (by up to 20 % in some locations), with much of the increase driven by intensification of the heaviest rainfalls.77, 78,79 This tendency towards more intense precipitation events is projected to continue in precipitation events is projected to continue in the future.80

The deuterium excess, a proxy of Greenland precipitation moisture source, switches mode within 1 - 3 years over these transitions and initiates a more gradual change (50 years) of the Greenland air temperature as recorded by water stable isotopes.

Water levels are influenced by the amount of evaporation from decreased ice cover and warmer air temperatures, by evapotranspiration from warmer air temperatures, and by potential increases in inflow from more precipitation.

But now the risk of fire is exacerbated by climate change, which heats air (stoking stronger winds) and water (leading to more evaporation and hence stronger precipitation events).

The shift can be explained by changing precipitation patterns and higher average temperatures that make moisture evaporate from the soil more rapidly than in the past, the study said.

Hundreds of millions of people in urban areas across the world will be affected by rising sea levels, increased precipitation, inland floods, more frequent and stronger cyclones and storms, and periods of more extreme heat and cold.

This allowed the development and validation of more realistic simulations that replicated the aircraft measurements and thus quantified more reliably the entities that can not be obtained directly by the aircraft measurements to improve understanding and modeling of aerosol - cloud - precipitation interactions.

The atmospheric warming is the factor that can best explain this consistency, up to ~ 0.7 °C since 1950 and more marked since 1976, while the trend in precipitation is much less homogeneous over this area and is affected by a significant decadal variability.

With the climate warming, extreme precipitation events may start happening more frequently, a paper published by the American Water Resources Association said.

Even in areas where precipitation does not decrease, these increases in surface evaporation and loss of water from plants lead to more rapid drying of soils if the effects of higher temperatures are not offset by other changes (such as reduced wind speed or increased humidity).5 As soil dries out, a larger proportion of the incoming heat from the sun goes into heating the soil and adjacent air rather than evaporating its moisture, resulting in hotter summers under drier climatic conditions.6
